This Tyrell posting by Virgin on Friday...
So how would Virgin choose to describe the even older Mk3s they use on their Pretendolino?
UPDATE: This from a Mr Brooks...
60010 is also a ‘Streak’ (A4 Pacific built by Sir Nigel Gresley) which is presumably where the ‘heritage’ label presumably comes in.
However, as its currently residing in Canada, it might be a bit extreme to suggest that its being towed in a consist over here - unless President O'Bama has included it in his entourage of many vehicles?
